Corrosion level classification:
Through many different ways, different degrees of protection can be achieved. Four types of corrosion protection are listed now
Level 1 (ISO Class 1)
Indoor fixation, with slight corrosion impact. Most galvanized nails/yellow zinc used for interior partitions belong to this grade. The thickness of the electroplating layer is 2-5 microns.
Level 2 (ISO Class 2)
Indoor fixation with certain corrosion requirements. Electrogalvanized/yellow zinc nails usually meet this level. The thickness of the electroplating layer is 10-12 microns.
Level 3 (ISO Class 3)
Indoor fixation, used for moderate industrial pollution and mild marine environments. This category is suitable for general roof and wall applications.
The 1000H anti-corrosion coating nail can meet and exceed this standard through salt spray testing by Pietro Kishbone and Japan's Laspex.
Level 4 (ISO Class 4)
Indoor fixation, used in mild and severe marine environments, classified according to ISO 9223 standard, generally between 100 meters to about 300 meters inland from the coastline. In windy environments, it can extend inland for a certain distance. Fasteners that meet the requirements of Class 4 anti-corrosion coating are used in conjunction with international standard steel (when used in coastal environments between 200 and 400 meters). Whether the selection of fasteners conforms to the usage environment should be tested and evaluated through real natural environment testing When conducting testing at an approved outdoor testing site, 95% of the surface of the fasteners to be inspected must not be covered with red rust. This type of outdoor testing site must be located no more than 500 meters from the coastline, in coastal areas with waves in most seasons of the year.
Pitt Kishbone and Japan's Lasspart salt spray test 1500H anti-corrosion coating nails can meet customer anti-corrosion requirements.

Kishbone Imported coatings from Japan
Kishbone low-temperature type is a surface treatment developed for rust prevention of steel products that are prone to changes in properties due to processing temperature.
Kishbone developed a chromium free and highly corrosive surface treatment technology for steel products that are prone to delayed damage caused by hydrogen embrittlement. It consists of two parts: a primer rich in zinc powder and aluminum powder, and a topcoat mainly composed of aluminum powder and organic resin. Qishibang low-temperature type is suitable for steel products where physical properties are prone to changes and processing temperatures are relatively low.
Technical feature
|
Hydrogen free brittleness treatment process
|
|
Due to the absence of electroplating pickling and electrolysis processes for steel, there is no need to worry about hydrogen embrittlement issues. Especially suitable for high carbon steel with high strength differentiation (chromium molybdenum steel and high tension steel)

|
Environmental ROHS Directive
|
High corrosion resistance
|
|
Not using hexavalent chromium, trivalent chromium, and six substances included in ROHS directives such as lead, radiation, and mercury Quality. Simultaneously comply with REACH instructions.
|
Transform the passivation treatment of the original Laspex into a chromium free special coating. The zinc coating is tightly combined with the topcoat to maintain the same performance as the passivation treatment.

Reduce electrical corrosion
|
|
The processing temperature below 200 ℃ will not affect
the physical properties of the product.
|
There are also low friction treatments that can reduce
the friction coefficient, including three types: low, standard, and highfriction.

Why is corrosion an issue that cannot be ignored?
For a long time, fasteners have been the weak link in all structural connections of buildings.
It is not a problem with the design or performance of fasteners, but rather a weakening of strength due to corrosion over time, resulting in the loss of fastening effect.
Generally speaking, corrosion is always associated with non rare metals such as steel, zinc, and aluminum. This type of metal is extracted from minerals and rapidly corrodes when air, water, or salt coexist. Under aerobic conditions, hydrides are formed, making the metal surface dull and ultimately leading to safety hazards or waste. Corrosion is a natural process that converts metals into minerals (initial state).
Fastener corrosion can be caused by salt mist from the ocean, gaseous acids from industry and chemistry, ultraviolet radiation from the sun, and moisture from tropical and humid regions. Corrosion greatly affects the performance of fasteners during their lifespan, which in turn affects the long-term structural integrity of buildings. Exposure to corrosive environments may lead to weakened performance, formation of cracks at the bearing area of fasteners, and ultimately failure.
The protective coating on the surface of fasteners follows the principle of "galvanic corrosion". This phenomenon occurs when two different metals come into contact in a corrosive environment. At this point, the more active metal corrodes before the less active metal. If the steel surface is galvanized, the steel is protected until the galvanized layer is completely corroded.
Through many different ways, different degrees of protection can be achieved.
